-vide a hose terminal, which, `when thevhose becomes damaged, can'bereadily removed and used again, and

thereby eect a considerable saving of expense in brake equipment forcars; to provide a hose terminal which is so constructed and arrangedthat the inner diameter of that end of the hose to which the terminal isattached will be or a diameter substantially equal to the inner diameterofl the remaining portion of the hoseto permit -pas'sage of liuidthrough the terminalas it enters `the hose, and to provide a hoseterminal, wh'ich, lwhen set up, will not mar or strip the inner liningof the hose. I

A `further object ofthe invention-is to provide a terminal 'wherebytheedge of that end of the hose to which the terminal is attachedv isprotected against fraying by asudden incoming supply Oiiiuidtherethrough. l.

Otherobjects ofthe'invention are to provide a hose terminal which willbe simple in construction,- easily positioned with respect to the end ofthe hose, durable, efficient in use, strong, and comparativelyinexpensive to manufacture.

With the foregoingandother objects in view, the

v invention consists oi the novel construction, combination andarrangement of parts hereinafter more Y specifically described andillustrated in the accompanying drawings, wherein is shown the preferredembodiment of the inventiom'but it is to be understood that changes,variations and modifications vcan be resorted to which come within thescope of the claims hereunto appended. f In describing the invention indetail reference is had to the accompanying drawings, wherein likereference characters denote corresponding parts throughou the severalviews, and in which- Figure 1 is a sectional view of a hose membershowing v the parts of the hose terminal in the act of assembling, and,Fig. 2 is a like view showing the parts assembled.

Referring to the drawings by reference characters, I

1. denotes the hose member, -which is formed of an inner lining 2, anintermediate portion 3 and a covering 4. In connection with the hosemember 1 it will be stated that generally the inner lining, as well asthe outer covering is of rubber, but the inner lining is formed of amuch better quality of rubber than the Speeication of Letters Patent.Application led October 1, `1906.

'louter covering. In some instances the outer covering 1 is of fabric.The intermediate portion is generally of' canvas. It is the moreexpensive inner lining which l it is'desi'redto protect againstinjury,since if the inner lining is punctured-or otherwise injured the air orother Huid will escape therethrough and through the intermediate portionand outer covering.

,A-hose terminal in accordance with this invention comprises an outersection 4 and an inner section 5,

between which the end of the hose member vis compressed.. The outersection 4 is cylindrical in contour and has its inner surface formed oftwo diferent diamel ters. That portion of larger diameter which visindicatedby the reference eharacter 7 is of greater length than theportion'of smaller diameter, which is indi' cated by the referencecharacter 8. The portion 7 its diameter substantially equal to the innerdia-meter of the hose member. By forming the inner surface'of slightlytapers towards the portion 8 and the latter hasl the section 4 of twodifferent diameters a shoulder 9 is Y provided, which acts as a shieldfor the edge l0 of the hose member to prevent the incoming fluid fromenv gaging the edge 10 of the# hose lto prevent stripping the latter.The direction in which the air travels is indicated by the arrow. Theportion 7 of the inner surface lof the section/1 is provided with aplurality of annular ribs 1I, which in connection with the inner section5 4and when the section 4 is in position, are adapted to ltightlycompress the outer lining of the hose member against the canvas portionand prevent the section 4 f rom being pulled OH the hose member 1. Whenthe hose member is secured between the sections, the end of the-hosemember is compressed inva wedge-like manner. Projecting lfrom the outerend of the'section 4 is a screw-threaded nipple 12. The'nipple may beinteriorly or exteriorly screw-threaded and as shown, is'interiorlythreaded. The function of the nipple 12 isV to connect the` terminalwiththe angle cock of the train pipe or with means for connecting theterminal to the angle cock or with the coupling between the two'hosemembers.

.The inner section 5 of the terminal consists of a non-l expansiblecylindrical bushing oi the same external diameter throughout its length,but of a slightly larger diameter than the inner diameter of the hosemember 1.v

The section 5 is of sufficient length to extend from the shoulder 9 tonear the inner end of thev section 4 to permit the hose to bend at theend of the section `4 without possibility of. injury-,to its innersurface by coming into contact with the inner end of the section 5. Apair of lugs 13 are formed on the inner surface of the section 5 topermit of a tool shifting the said section 5 to operative position withrespect to the section 4.

The end of thev hose member to which the terminal is attached iscompressed between the sections 4 and 5, and when the terminal is inposition, the inner surface consisting' ot' an outer cylindrical sectionhaving its inner' .umeter slightly tapering towards the free end of saidsecoi the section 5 is flush with the inner surface of the portion 8 ofthe section 4, and said section 5 has its outer edge in close proximityto the shoulder 9. A

When assi rbling the terminal on the end of a hose the section 5 is rstslipped within the end of the hose some distance beyond the end of thehose, as shown in Fig. l, said section 5, as before stated, having anexterior diameter slightly larger than the interior diameter of thehose; the section 4 is then positioned upon the exterior of the hose atthe end thereof; the section 5 is then pulled towards the shoulder 9 bymeans of a suitable implement, and the hose member is thereby iirmlycompressed and clamped between the sections 4 and 5. When the section 5is drawn towards the shoulder 9 there is no flaring outwardly of theendiof the hose upon which, the terminal is mounted. The hose is simplycompressed between the two sections. Owing to the fact that the outersurface of the section 5 is smooth, there is no liability of strippingor injuring the inner lining of the hose member l, and since the edge l0of the hose member is protected by the shoulder 9 and also protected bythe forward end of the section 57 said edge l0 is protected againstfiaying by a sudden incoming supply of iiuid.

What I claim is- 1. A terminal for a hose member' of a train pipecoupling' to prevent the stripping or" the member' by the incoming air,

surface of two diil'erent diameters to form a shoulder', the portieri ofsmaller' diameter being,r substantially equal to the inner diameter ofthe hose member and through which the air enters the hose member, theportion of larger dition and having.: a plurality of ribs adapted toengage in the periphery of the 'hose member when the said section lsomos is in operative position, said shoulder adapted to abut againstthe edge of the hose member when the said section is in position, and aninner annular' non-expansibie section having its outer diameter greaterthan the inner' diameter of the hose member and adapted to compress thehose member in a wedge-like manner between it and suld outer scction,said inner section extending from the shoulder' of the outer section tonear the inner end of said outer section, and having its inner diameterthe same as that portion of smaller diameter of the outer section.

2. A terminal for a hose member of a train pipe coupling to prevent thestripping of the member by the incoming air from a source of supply,consisting of an outer cylindrical section having its inner surface oftwo diier'ent diameters to for'm a shoulder, the orrter' diameter' ofthe major portion of said section being,r substantially equal to theouter diameter' of the hose member', that .portion of smaller diameterof the inner' surface ot' said section being substantially equal to theinner diameter'of the hose member' and that portion of larger diameterof the inner' surface of said section formed with a plurality of ribsadapted to engage in the periphery of the hose member when the saidsection is in its `operative position, said shoulder adapted to abutagainst the edge of the hose member when the said section is inposition, thereby preventing the strippini,r of the end of the hosemember by the incoruiugair, and an inner non-expansible annular' sectionhaving its outer dl- :rrneter greater than the innerI diameter of thehose memner' surface by coming in contact with the inner end of the
